Gday JM, when I bought my 2020 Ultra Limited it came with 2 sets of the standard plug in HD headsets just the same as my previous Ultras. I did inquire about the whim and Sena set ups but I'm a tight arse and just use the standard sets. I think the only thing I can't do is speak to other riders. (years ago a lot of us around here had the old 27mhz CBs fitted and they worked well. HD fitted that CB radio as standard to the Ultras back then, but not now , everyone commented on how clear mine was.) With our plug ins my wife and I have, we enjoy very clear intercom between ourselves. I paired my mobile into the radio and can answer and dial any of the numbers on my phone plus get text messages .............. again perfectly clear all the time and it just lives in my top pocket or plugged in if it needs charging. As far as music goes I have a thumb drive (with 1200 songs on it, we love our music ) permanently plugged into the USB thingie  in the R/H side of the batwing.

Hey guys I have a 2023 Ultra Limited with the WHIM installed and have successfully paired a Cardo Freecom 2X to the boombox and also have a Quadlock wireless carplay installed. I use the bikes speakers for music usually spotify from carplay and only use the Cardo for SIRI commands and turn by turn navigation commands. I am waiting on 2 new helmets and then I'll install both Cardo units in for the wife and I and will test rider to passenger comms and let you know if that works. I am not concerned with Mono music via the headsets as I'll continue to use the bikes speakers.

I did a bit more digging and it seems that AndriodAuto is programmed to ignore any external speaker/mic system and use the vehicles, but it took a couple of mins for it to kick in and re-route from my headset back to the bike.

I am wondering if AppleCar Play does the same thing for iPhones? I haven't tested that yet.

But if there was a way to "hack" AndriodAuto to force it to pipe audio through to an external headset we could just use that linked with our smartphones to get the same or better functionality out of the BoomBoxGTS.

I will continue to explore this avenue as the alternative that we are forced to tolerate is less than ideal in 2023.

Not giving up on this haha and found this thread by Ryan Urlacher on his Law Abiding Biker channel, has anyone tried this trick on the latest version M23.22.27.00, with CarPlay or AndriodAuto?

"When the Boom Box GTS was first announced for 2019 and newer Harley touring models you needed the above items in place [WHIM & HD Branded Sena] to get Apple Car Play to activate. With software updates Harley has recently put out, you can get Apple Car Play to work with a simple trick I found. You don’t need the Harley headsets or the WHIM, but you do need to take your Harley to a dealership so they can plug it into their proprietary Digital Technician II software and check a box to tell your Boom Box that you have a WHIM, even if you don’t. By doing this, it activates Apple Car Play on the Harley Boom Box GTS and you can then begin using it. Don’t forget to go into your Harley Boom Box GTS setting and turn on “projection” mode, so it mirrors your iPhone. And remember that your iPhone has to be plugged directly into the Boom Box USB interface to activate Apple Car Play. It does not work if your iPhone is paired to the Boom Box GTS via Bluetooth. ... Remember that if you flash your Harley Boom Box for the WHIM, you won’t have to go back to a dealership in the future if you ad the WHIM for wireless Bluetooth headset pairing with your Harley Boom Box GTS. This trick is working with Harley Boom Box GTS software Version MY19.19.03.00. This could change in the future with software updates, so always save each software update version, so you can always revert ..."

Hey JM,
